jBeginning in 2009, includes wind energy consumed by the commercial and industrial sectors. From 1981 through 1992, includes fuel ethanol blended intomotor gasoline that is not included in the motor gasoline column. Beginning in 1980, adjusted for the double-counting of supplemental gaseous fuels, which areincluded in both natural gas and the other fossil fuels from which they are mostly derived, but should be counted only once in net energy and total.

cLiquefied petroleum gases, includes ethane and olefins.

kIncurred in the generation, transmission, and distribution of electricity plus plant use and unaccounted for electrical system energy losses. Pre-1990estimates are not comparable to those for later years. See Section 6 of Technical Notes for an explanation of changes in methodology.

dBeginning in 1993, includes fuel ethanol blended into motor gasoline.

– – = Not applicable. NA = Not available.

eIncludes asphalt and road oil, aviation gasoline, kerosene, lubricants, and the 16 other petroleum products as described in the Technical Notes, Section 4,"Other Petroleum Products."

Where shown, R = Revised data and (s) = Physical unit value less than 0.5 or Btu value less than 0.05.

fConventional hydroelectric power. For 1960 through 1989, includes pumped-storage hydroelectricity, which cannot be separately identified.

Notes: Total end-use consumption estimates are the sum of the consumption estimates for the residential, commercial, industrial, and transportation sectors.· Totals may not equal sum of components due to independent rounding. · The continuity of these data series estimates may be affected by the changing datasources and estimation methodologies. · See the Technical Notes for each type of energy.

gThere is a discontinuity in this time series between 1988 and 1989 due to the expanded coverage of renewable energy sources beginning in 1989.
